autometer water temp gauge not working

• 2022-02-21

The failure of the cooling fan will cause the heat generated during the medium and high operation speed of the automobile engine to be transferred to the antifreeze without timely heat dissipation, resulting in the rise of the antifreeze temperature, which will lead to "boiling" and other problems. Be sure to pay attention to the temperature of the antifreeze on the way. If any abnormality is found, first reduce the speed and stop the vehicle, but do not turn off the engine, and check whether the cooling fan and circulating water pump are faulty.

There are few cases of bearing locking. Once this happens, the timing belt will be damaged, or the engine valve will be jacked by the piston. Moreover, most of the water pump bearings are maintenance free bearings, which will make abnormal noise before locking or cause water leakage of the water pump due to eccentric wear of the bearing.Therefore, the water pump shall be inspected during daily inspection or routine maintenance, and the water pump shall also be inspected when replacing timing belt and other relevant parts. When there is abnormal noise near the water pump, pay attention not to mistake the sound of the transmission belt slipping as the sound of the water pump.

The common forms of impeller damage include impeller cracking, impeller loosening from the pump shaft or impeller corrosion. Impeller corrosion generally will not cause engine failure. After the impeller cracks or the impeller looses from the pump shaft, the coolant circulation speed slows down, which is easy to cause the fault of excessive engine temperature. The damaged impeller may also hit the water pump housing during rotation, causing the housing to break.Impeller damage is usually caused by abnormal high temperature in the engine, and some are due to the quality problem of water pump impeller. When checking whether the impeller is damaged, most water pumps can only see the condition of the impeller after removing it. Some engines can touch the water pump impeller by hand after removing the thermostat.

The water temperature gauge doesn't move, and the car can continue to run in a short time. The reason why the water temperature gauge doesn't move may be that the water temperature gauge or temperature probe is broken. As long as the water tank is not short of water, the normal driving will not be affected. It is recommended not to operate at full load before troubleshooting. Whether the fuel consumption is irrelevant to the movement of the thermometer, but related to the operation condition of the vehicle.
